A new study shows that being a couch potato may shorten your life.
The new study which included only Australians shows that those who watch TV for four hours a day or more had a 46 percent increased risk of death from any cause and an 80 percent increased risk of death from cardiovascular disease, compared to those who watch less than two hours of TV a day.
Live Science reports those figures do not even take into consideration other independent risk factors like poor diet, high blood pressure and smoking.
Researchers said one of the main reasons watching excessive amounts of TV is bad is that it takes time away from much needed exercise.
"What has happened is that a lot of the normal activities of daily living that involved standing up and moving the muscles in the body have been converted to sitting," David Dunstan, study author and researcher at the Baker IDI Heart and Diabetes Institute in Victoria, Australia, said in a statement.
"Technological, social, and economic changes mean that people don't move their muscles as much as they used to, and consequently the levels of energy expenditure as people go about their lives continue to shrink," he added.
